Someone on AskReddit asked for parents to share their harrowing experiences with what drove them to disown their children. The resulting stories are pretty dang heartbreaking. Proceed at your own risk. 

Text - willmaster123 16h I went out with a woman who had a 22 year old son that she disowned forever. She didn't like to talk about him at first, but one day she just told me that she caught him molesting his 8 year old cousin when he was 20 years old. While the rest of the family was having dinner downstairs, including the 8 year olds mother. I didn't ask anything more than that.
